One of my small danio fry has developed two black lines from gill to tail, looks like he is a D. Nigrofasicatus
Plus five more eggs in the filter today, amazing as we didn't see them breeding at all last week.
Since setting up my filter collection method I am beginning to get the sort of problems with Danios that I have only had before with guppies. (hint Rabbits!)
If it carries on like this I will be looking for new homes for some of them, watch this space!
